Nope I'm using the 30xWA eyepiece as I couldn't zoom out the vignetting on the 20-60x. I gave the 20-60x a go the other day but binned the photos as even when zooming to reduce vignetting the shadow is still visible as well as it affecting exposure.
With the 30x you get negligible vignetting at zero camera zoom but it goes altogether at around 1/3 camera zoom - basically one zoom activation - though it's not as smooth as the CP4500. Zoom needs to exceed the macro setting for vignetting to disappear.
I'm using the Swaro ATS80HD - other scope brands with wider eyepieces would have less problems.
